# Downloads and printers

## Formats

- **3MF for your printer**: the box centred on your printer's bed, with the settings you picked (Standard, Fine, Draft or Strong) and no brim. Open it in your slicer and slice. See [Printers and 3MF downloads](/docs/guides/printers-and-3mf) for what each setting means.
- **STL**: a closed, watertight mesh that any slicer opens without repairs.
- **GLB**: for web 3D viewers, AR on phones and design tools. It's in metres, as GLB expects, so it shows at the real size.
- **Screenshot**: the camera button saves a PNG of whatever view you're looking at.

## How many downloads?

- **Free plan**: 3 downloads a month, in any format. The count starts again on the first of the month.
- **Paid plans**: unlimited.
- **Screenshots** never count.

## Doesn't fit your printer?

The line under the printer list turns red and says which size is too big. Make the box smaller, or pick a printer with a bigger bed. Turning the box 90° on the bed already counts, so you don't need to swap length and width yourself.
